lCRIIVIPING APPARATUS FOR BOOTS AND SHOAS.

SPECIFICATION forming part of Iietters Patent No. 291,017, dated January1, l84.

' Application filed May 7, 1883. (No model To @ZZ who/1t it may concern:

Be it known that I, HIRAM R. ADAMs, of Boston, county of Suffolk, Stateof Massachusetts, have invented an Improvement in Ap- 5 paratus forCrimping Boots and Shoes, of f 'which the following description, inconnection with the accompanying drawings, is a specification, likeletters on the drawings representing like parts. n, .Boot and shoeuppers arenow usually crimped by placing the same in a crimping-machine,where they are engaged by a form and forced between jaws which stretchand fit the upper to the form as the latter is forced between and belowthe jaws. In this common method of crimping, the entire crimp impartedto the upper is given to it by one continuous passage of the upper actedupon by the form between the jaws, and the movement of the parts beingrapid itis found impracticable to give to the upper but a limited amountof curve, and even with but little curve the uppers are frequently tornand injured, and the operation being quickly performed the leather hasno 5 chance to set, and much of the stretch put into it while beingpassed between the jaws is lost as soon as the upper leaves the jaws. Inaccordance with my invention I have pivoted the foot of thecrimping-form to the leg, so that when the edges of the upper areattached to the said foot and leg in their nearly straight condition therelative positions of the foot and leg are changed, gradually forcingthe foot into a position more and more nearly to a right angle to thefront of the leg part of the form, the said leg part being of greater orless length. During the forcing ofthe foot into its eect- `iveposition,77 as I shall call it, the upper is acted upon by a `suitablerubbing device-Aa `wheel or stick in thehands of or controlled by anoperator+-and the upper is thus gradually l crimpedandthewrinkles,rubbed down and "but: giving ELDlllvlulent lshape'aud setto the J leather.4 f w. s

f `In my inverni-.mayasherein embodied, the

n uppermaybe lasted andat the same time be crimped, so that it may beapplied directly to a last having a suitable inner sole, and the 1flanged or turned-over edges of the upper will 5o be in proper stretchedand bent condition to be united with the soles, the soles being unitedby staples, as in my Patent No. 262, 552, or by any other usualfasteners. My invention consists, essentially, inabootcrimping formcomposed of a leg and a foot 5 5 pivoted thereon, and adapted to beturned the one with relation to the other and both upon a common pivot,as will be described, to gradually effect the crimping operation, also,in a pivoted crimping-form having a pivoted 6o foot, combined with meansto change the relative position of the said foot and leg to graduallyeffect the crimping operation.

Figure l is a longitudinal sectional view of a boot-crimping apparatusembodying my invention; Fig. 2, a rear side or edge view of the leg andfoot removed from the leg-holder, and Fig. 3 a detail showing part ofthe soleplate of the foot with upper engaging orholding devices thereon.

The'foot A, preferably made last-shaped and as a cast-metal shell, isconnected with the leg part B, also preferably made hollow and of castmetal, bya pivot-pin, C, or'other suitable hingej oint, care being takento avoid as much as possible seams or spaces at the junction of the footand leg to keep the leather smooth at that point. The leg part isattached to the leg-holder D by suitable screws or bolts, a, the saidleg-holder having an ear, b', boredto fit 8o the guide-rod b2, to whichit is rigidly attached, the said rod being placed loosely insuitablelugs or brackets, b 1f, bolted to abcd or bench, E, by bolts d. The rodbZ serves asV a guide for a yloose collar, e', having pivoted upon itone linke2, of a toggle-jointed lever, e? e3, the member e being pivotedon the ear b3. The central pivot, c5, is connected with ablock, e,having attached to it a rod, 5*, which will be operated by a treadle sopivoted that the pressure of the foot on the treadle will move the rode4 in the direction of the arrow thereon, and cause the collar e toforce the head or cam block f in the direction of the arrow on it, sothat the said block placed loosely on the rod b", and acting on theextension g ofthe foot, will turn it gradually from its dotted to itsfull line position. The leg has flanges h, extended down into the footbelow the pivot C, and slotted, as shown at h2 in Fig. l, to receiverods ha, having on them at the sides of the flanges suitable collars, hThe bottom of the foot will be provided with a series of upper holdersor clamps, B, substantially as shown in another application filed by me,wherein the same letter is used. The upper will have its edges clampedto the foot and leg, while the foot is in its dotted-line position, andthen the toggle-lever will be gradually moved from its dotted to itsfull line or effective position, bringing the foot into its full-lineposition; and during this operation the operator will rub the upper onthe foot and at the junction of the foot and leg, gradually iitting theupper to the foot and leg as their relative positions arechauged. Duringthe operation the operator will rock the leg-holder I) and form, so asto place iirst one and then the other side of the form uppermost or inthe most handy position to rub the upper, and during this time the blockj" is also rocked ou the rod b in unison with the form.

I do not limit myself to the exact upperholding devices shown, andinstead of them I may use any other suitable holding devices, or mayengage the edges of the upper with pins yn, on the leg and foot. I donot desire to l. A boot-crimping I'orm adapted to be turned laterallyupon a longitudinal pivot and having its foot portion pivoted to the legportion, combined with means, substantially as described, to graduallyforce the foot portion more and more nearly into a position at rightangles to the leg portion to crimp the upper, as set forth.

2. In a crimping apparatus, a leg portion and a foot portion pivotcdthereto, combined with a rod, If, on which said leg portion has alateral rocking movement, and a block movable longitudinally of said rodand engaging the foot portion to force it into a position more or lessat right angles to the leg portion, substantially as described.

3. In a crimping apparatus, the leg and pivotcd foot and leg-holder andthe rod or guide to pivot the leg-holder, combined with means toautomatically operate the foot, as described, while the crimping-'formis free to be rocked or turned with the said rod, substant-ially asdescribed.

In testimony whereofl have signed my name to this speciiication in thepresence of two subscribing witnesses.
